Size: very small
The Robber? fly was probably only 10-15 mm, I didn't see the prey till I had the macro lens on it magnifying the image.

Prey Prey Prey

Moved from Braconid Wasps.

The braconid in the image ...
.. belongs to either the subfamily Opiinae or Alysiinae.

NB: Both of these subfamilies are parasitoids of flies, so the fact that another fly is attacking the brac is really completing the circle of life ... or in this case ... death.

Although these were not determined by Paul Marsh, I think this category is the best spot to place these images.

Debelytedly fulfilling.

Moved from Belyta.

thank you


Moved from ID Request.

the prey looks like a cynipoid to me

This time I think it really it could be braconid, but maybe the fly is better qualified to discuss its preferences than I am.

a few more photos with very little more information then the ones I posted, I think this braconid, with it's wing veinings, the hairs at the edge of the wings, and the eye pattern are the same as mine

The Robberfly seems really close to the same one I have too.

That's the story of my life. My problem seems to be that I have a braconid death wish.

any particular
type of critter you'd like me to post for you?

I'm probably 100 incests backlogged at this moment.

I posted this one as the curator of the natural history museum at UCSC was interested in knowing what we'd found.

Well, my BG bailiwick is the largest family of Hymenoptera, the Ichneumonidae, but my ability to help with photos of California species is limited by the fact that the species represented in my collection are from the northeastern part of the country.

which is
Probably why most of the photos I wind up looking at are from the NE USA..... Well, I'm adding what I can!

I suspect that not to be why there are so many from the Northeast. A fair share of the photos are submitted by folks that don't know the family, and my hunch would be that the geographic distribution of those would not differ from that for the images where the submitters knew the family in advance.
